What Is Bio Generator?

The Social Media Bio Generator creates platform-optimized bios tailored to each social network's character limits and culture. Your bio is often the first thing people read about you — it needs to convey who you are, what you do, and why someone should follow you, all in a very limited space. This tool generates multiple bio options for 6 platforms (Instagram, Twitter/X, TikTok, LinkedIn, YouTube, Pinterest) in 5 different tones (Professional, Casual, Witty, Inspirational, Minimalist). Each template is designed with the platform's specific character limit in mind — from TikTok's 80 characters to LinkedIn's 2,600.

Technical Guide

Bio character limits vary significantly: Instagram 150, Twitter 160, TikTok 80, LinkedIn 2,600, YouTube 1,000, Pinterest 500. Each platform has its own culture and expectations. Instagram bios work best with emojis, line breaks, and a link. Twitter bios should be concise and personality-driven. LinkedIn bios (the headline + about section) should be keyword-optimized for professional searchability. TikTok bios need to be extremely concise. Our templates use variables like {role}, {industry}, {value}, and {hobby} which are replaced with your inputs. The tool adapts template complexity to match each platform's character limit.

2

3
Add a call-to-action when the platform allows it (especially Instagram)
4
